Title: Display of electronic balance
Inventor: KAWAMOTO AKIRA
IPC: G01D7/00
Filed: 1982-04-28
Abstract: PURPOSE:To obtain a display of an electronic balance efficient and easy to use, by providing in juxtaposition a digital display apparatus of weighing with an analogue display apparatus corresponding to a figure of a part of this display quantity. CONSTITUTION:In case of weighing only 2350.0g of a liquid, a figure of an analogue display is set at two figures from the lowest figure. When the sample liquid is poured at the speed of about 500g in every one second at first, reading is made possible because the highest figure of a digital display 4 is increased by every one figure in about tow seconds. When its number is displayed as 2, the pouring velocity is decreased to about 100g per second and when the numeral of the second figure from the highest figure is displayed, the pouring velocity is decreased to about 10g per second. Because the reading of the numeral of the fourth figure is made impossible when the numeral of the third figure from the highest figure is dispayed, attension is given to an analogue display 5 when the numeral 4 of the third figure is dispalyed and the pouring speed is decreased when it is displayed about a half of it. Then, the digital display becomes to show 2350.0g when it is stopped exactly at a full scale. Hereby, the display apparatus having good efficiency and easy to use, is obtained.

Title: Marking apparatus for semiconductor wafer
Inventor: OKAZAKI HARUHIKO
IPC: B23K26/00
Filed: 1988-03-25
Abstract: PURPOSE:To cause a laser to output laser beams of power optimum for film properties of a semiconductor wafer and to enable the semiconductor wafer to be engraved uniformly independently of the film properties, by detecting reflected light from the semiconductor wafer, recognizing a ratio between quantities of incident light and reflected light and automatically correcting the power of laser beam based on a result of the recognition. CONSTITUTION:In order to detect film properties of a semiconductor wafer 7, a movable mirror 1 is moved to the position where it intercepts a first optical path 9 so that the laser path is altered to a second optical path 10. One laser beam which has passed through an attenuating filter 3 is reflected by a half mirror of 1:1 and incident into a power monitor 5 for measuring incident light quantity. The other laser beam is reflected by the semiconductor wafer 7 and is incident into a power monitor 6 for measuring reflected light quantity. Absorption coefficient of the semiconductor wafer 7 can be obtained by comparing the quantity of laser light incident into the power monitor 5 with the quantity of laser light incident into the power monitor 6. Since relation between the power of laser light and an engraving depth in the semiconductor wafer 7 is determined by the absorption coefficient of the wafer, the power of laser light can be determined such that the laser beam engraves the wafer always in the same depth.

Title: Manufacture of thin-plate shaped resin bonded type rare earth magnet
Inventor: SAKATA MASAAKI
IPC: H01F41/02
Filed: 1989-03-24
Abstract: PURPOSE:To manufacture a high-performance thin-plate shaped resin-bonded-type rare earth magnet by performing extrusion molding for a molding material comprising rare earth magnetic powder and an organic resin, forming a cylindrical magnet having anisotropy in the radial direction of the diameter, cutting the magnet in parallel with the central axis of the molded body, expanding the molded body, and obtaining the thin-plate shape. CONSTITUTION:Magnetic powder and an organic resin are sufficiently kneaded. Thereafter granulation is performed. The granulated magnetic composition is put into an extrusion molding machine and heated in a cylinder 102. The composition is made to be a fluid state and sent into a metal mold 105 with a screw 103. The magnetic composition passes through the metal mold 105 on which a magnetic field is applied. Thus, the axes of easy magnetization of the magnetic powder in the raw material are oriented, and the magnet is molded. A molded product 109 is cooled and hardened when the magnet composition is in the magnetic field formed in the metal mold 105. The product 109 is pushed out. One or a plurality of places on the circumference of the cylindrical molded body 109 are cut in parallel with the central axis of the molded body. The molded body 109 is heated. When the viscosity of the molded body 109 is decreased, the molded body is expanded into a thin-plate state. In this way, the thin-film state resin-bonded-type rare earth magnet characterized by the high magnetic performance can be manufactured with excellent productivity.
